specification.

" This invention consists in a locomotive truck, e.- 9,, an electriobatterytruck rovided with an attachment by means 0 which material a may, not only be. transported from place .to plaoeb'ut may also be lifted, loweredjand supported to and'at any point within predetermined limits while remaining, parallel to itssupporting surface. Although primarily intended. for the vhandling and conveyance ofsteel slabs .from the shears to the heating chamber of-a furnace, and the subsequent withdrawal of "the pieces from the furnace and trans rtation to the rolls of' a sheet rolling mil i yet it may also be applicable to the hand mg of a vvariety of other materials. y the substitution of suitable forms'of g rip.

' imeording.- to one embodiment there is erected u on the platform Oran electricbat tery true a framework which serves to sup: port a rope or chainbarrel'driven' through suitable toothed orgfriction gearinghymn electric or-other motor. Tosuitable. points on the same framework are attached parallel levers, the free ends of which are connected to :a detachable'grip or jaw. Around the barrel is coiled a rope or chain attached to the parallel levers at points intermediate the gri or i aw and the points of'attaehment to the. Framework. A brake is provided for sustaining' the load when the motor is at rest. Assurning that it i s'desired' to charge a furnace. from a pileof steel pieces cut. to the requisite size, the truck is driven to thepile of steel, and the operator, raising, or lowering; the gri or jaw to' a height suitable for engagingt 0 piece to be handled continues to move the truck forward until the rip is in'engagement with the steel piece, w en he -raises it from the pile and conveys it to the .fllrnaceinto which it is placed as' desired on reversal of the series of o erations. It will ;be seen that the load is a ways carried paring upon the drum F, t

allel to its'original position, i. a, receives translatory movement only whether raised to its full extent'or lowered to ground level. When a furnace is being discharged the truck is maneuvered so that the grip enters the heating chamber, thereafter engaging and lifting'the steel piece as before, Where upon the truck is withdrawn from the furnace with its lead and it conveys the load to the rolls or the like to the foreplate of which it is lowered by means of the auxiliary motor. l

Referring to the drawings Figure 1 is an elevation and Fig. 2 is a plan showing the complete mechamsm. Fig. 3 is a diagrammatic representation of a modified construc tion and Fig. 4 is a detail viewof an alternaframework C supporting parallel levers B,

B provided with a detachable grip or jaw A. Carried on the framework C. is an electric-or other rotary motor E arranged to drive a ropeor chain-drum F-through the intermediary of gearing G; H, J, K. Embracing the drum F is a rope or chain L passing over a pulley M and attached at one end to a crosshead N fitted to the levers B, B at the end remote from the drum F. With the grip A at a convenient height the truck I) may be maneuvered until the grip 'A engages the pieces to be handled whereupon. the motor E isrotated clockwise and the levers; B, B carrying the grip and its.

load; are raised by the rope or chain L coile load being con strained to perform translatory movement in a position such as is shown by the dotted lines. A brake Q-is provided for the purpose of sustaining the load automatically or otherwise, whenthe motor Eis stopped,

Although for simplicity the arrangement of gearing shown is preferred, it is to be understood that the invention is not limited to this construction and that the drum F may be driven from the motor .E by s ur, worm, friction or bevel gearing. As sh wn in Fig. 3, the rope or chain for lifting may be dispensed with and an end of one of the levers B, B may be attached directly orthe driven shaft S, the free lever B, being piv f oted on the framework to actas a guide insuring parallel movement.

and ha ving a 'rectly connecte As shown in Fig. 4, the movement of the lovers B, B is controlled by a steam, a hyiraulic or a compressed air cylinder R, such cylinder 1R being mounted upon the truck lston T with a rod T dito extensions of the levers B, B and so arranged that the movement of the piston rod T will be accompanied by cor responding raising or lowering movements of the load supported by the remote ends of the levers.

The truck being trackless is capable of bein steered in any desired direction.

1. A handling and transporting device, comprising, in combination, a locomotive truck, a. framework on said truck, a system of parallel levers ivotally mounted on said framework and including a cross-head, a gripping device carried b said. system and comprising jaws adapte to seize and hold an article to be transported, a winding drum on said framework, a motor for operating said drum, n loadsustaining brake, and flexible means operntively connecting said drum with said cross-head for moving said system on its pivot.

A handling and transporting device, comprising a locomoi i e truck, a framework on said truck, a system-0f parallel levers pii" otally mounted on said framework and com prising a cross-heed, a gripping device cai ried by said system and comprising jaws adapted to seize and hold an article to be tmnsported, and actuating means for said system comprising a motor on said frame work, a winding drum operatively connected to said system through said cross-head, and gearing connecting said motor with said drum, in combination with a load-sustaining brake cooperating with said drum.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
